摘　　要：介绍了一种基于 PC/10 4总线 ,具有 GPIB程控功能 ,采用无内部微波源体制 ,通过在雷达载频上调制多普勒频率模拟目标速度信息 ,延迟雷达发射机触发脉冲模拟目标距离信息并具有微波功率精确定标与衰减功能的A moving target simulation and microwave instrumentation system of PD radar is presented. The system, without the inner microwave source, is based on PC/104 bus , and can be programmed with GPIB . It can simulate the target′s velocity by modulating the doppler shift on radar′s carrier frequency, and can simulate the target′s range by delaying the radar transmitter trigger. Power of microwave can be measured and attenuated precisely.
